A pulley device is used to launch projectiles from a ramp, as shown in the diagram. A mass of 5.0 kg is accelerated from rest at the bottom of a 4.0 m long ramp by a falling mass of 20.0 kg suspended over a frictionless pulley. Just as the 5.0 kg mass reaches the top of the ramp, it detaches from a massless rope and becomes projected from the ramp. The coefficient of friction between this mass and the ramp is 0.26. Block a) Find the acceleration of Block 1 along the ramp. [3] b) What is the speed of Block 1 when it reaches the top of the ramp? [1] c) When Block 1 reaches the top, it launches off the ramp as a projectile. What is the maximum range of this projectile from the ramp? [1]
